沿海水闸防渗系统修复技术

Repair technology of anti-seepage system of coastal sluice

本文根据沿海地区水闸内外水位差大、地质情况复杂的情况,对拉森钢板桩防渗墙技术结合高压注浆防渗修复方案进行了实用性论证,提出了施工程序和注意事项,可为类似水闸工程渗径不足的处理方案提供经验借鉴。

Larsen steel sheet pile cut-off wall technology is combined with high pressure grouting anti-seepage repair plan for practical demonstration in the paper, according to large difference of water level inside and outside coastal areas sluice as well as complex geological condition. Construction procedures and precautions of the measure are proposed, thereby providing experience for treatment scheme with insufficient penetration path in similar sluice projects.
